    Electronic effects of sodium in epitaxial CuIn1−xGaxSe2 (1997)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 82 (1997), S. 4982-4985

    Notes: Temperature dependent Hall effect measurements were made on Na-contaminated and uncontaminated epitaxial p-type CuIn1−xGaxSe2 films. Na was introduced by diffusion into as-deposited samples using both NaOH and Na2Se as sources. Na concentrations were measured using secondary ion mass spectroscopy by comparison to an implanted standard. Films contaminated with Na from either source were found to have much lower compensating donor densities than as-deposited films. Oxygen and other impurities were not found to be necessary to produce this effect although some changes with Se content were observed. These were independent of the Na effect. © 1997 American Institute of Physics.

    Hole transport and doping states in epitaxial CuIn1−xGaxSe2 (1998)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Temperature dependent mobility, resistivity, and carrier concentration measurements were made on epitaxial single crystal thin films of group III-rich CuIn1−xGaxSe2 (CIGS). The films were produced using a hybrid sputtering and evaporation process on GaAs substrates. Samples with average Ga/(In+Ga) values between 0.03 and 1.0 and Cu/(In+Ga) between 0.73 and 1.00 were measured. All films were p type with room-temperature carrier concentrations between 4×1016 and 2×1019 cm−3. Fits to electrical measurements were consistent with the presence of two acceptor levels, with activation energies of 167±20 and 42±8 meV at low Ga contents, and compensating donors in all samples. Increasing Ga content was found to increase acceptor density and decrease acceptor level depth. Hole mobilities near room temperature were found to be between 167 and 311 cm2/V s and peak mobilities were between 439 and 1760 cm2/V s. Mobility behavior did not change significantly as a function of composition or the presence of a Ga gradient. © 1998 American Institute of Physics.

    Gallium diffusion and diffusivity in CuInSe2 epitaxial layers (1996)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 69 (1996), S. 4068-4070

    Topics: Physics
    Notes: Ga diffusion in single crystal Cu(In1−xGax)Se2 (CIGS) epitaxial layers on GaAs was measured as a function of the Cu/In ratio in the CIGS. No Ga was supplied intentionally during deposition but Ga was released by the substrates into the growing film. The concentration profile of the Ga was determined by secondary ion mass spectrometry and was fit by numerical solution of Fick's second law including motion of the surface and the possibility of Ga desorption from the surface. All films studied had Cu/(In+Ga) ratios greater than 1.0, which was determined by the Ga outdiffusion from the GaAs. The Cu/In ratio was controlled by the deposition conditions. The Ga diffusivity was a minimum near a Cu/In ratio of 1.0 and increased rapidly for both higher and lower values of this ratio. The diffusivity ranged from a minimum of 2.7×10−13 cm2/s at Cu/In=0.94 to 5×10−11 cm2/s−12 cm2/s at Cu/In=1.41 and 7×10−12 cm2/s at Cu/In=0.43. It was concluded that Ga diffuses on metal vacancies on either the Cu or In sublattice. © 1996 American Institute of Physics.

    Management, Theology and Moral Points of View: Towards an Alternative to the Conventional Materialist-Individualist Ideal-Type of Management* (2005)
    Oxford, UK : Blackwell Publishing Ltd.

    Notes: abstract  Weber's (1958) argument suggests that there are four ideal-types of management, and that conventional management is underpinned by a moral-point-of-view associated with a secularized Protestant Ethic, which can be characterized by its relatively high emphasis on materialism (e.g. productivity, efficiency and profitability) and individualism (e.g. competitiveness). Weber calls on management scholars and practitioners to become aware of their own moral-points-of-view, and to develop management theory and practice that de-emphasizes materialism and individualism. Our paper responds to this challenge, as we draw from an Anabaptist-Mennonite moral-point-of-view to develop a radical ideal-type of management that is characterized by its emphasis on servant leadership, stakeholding, job crafting and sustaincentrism. Implications for management theory and practice are discussed.

    Notes: An estimated 30 million people make use of the Internet not only for electronic mail (e-mail), but also to peruse databases, view photographs and videos and find travel information and weather reports. Innovative data systems managers can offer business solutions by integrating the capabilities of the Internet into their business environment. The Internet offers vast communication resources to enhance product development and system support. Offers an introduction to the communication resources of the Internet and provides several specific examples of business solutions in the areas of e-mail communications, business applications software support, system design and databases. An awareness of these global solutions by today's managers may stimulate an increased appreciation of the power of electronic communications and an encouragement of co-operative work, using electronic media.

    Potential transformations of chromium in natural waters (1975)
    Springer
    Water, air & soil pollution 4 (1975), S. 355-365 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract A study has been conducted on the transformation of Cr(III) and Cr(VI) in simulated natural water conditions. It has been found that these forms are readily interconvertible under natural water conditions. The results of this study indicate that Cr(VI) is reduced by Fe(II), dissolved sulfides, and certain organic compounds with sulfhydryl groups, while Cr(III) is oxidized by a large excess of MnO2 and at a slow rate by Oz under conditions approximating those in natural waters. Based on the results of these studies, water quality standards for Cr should be based on total Cr rather than on Cr(VI), as has been frequently done in the past.

    Description: Wie verändern sich Leitstellen, Notrufzentralen und Schaltwarten, jene hochgradig diversen Räume, die für das reibungslose Funktionieren von Infrastrukturen wie Strom, Verkehr oder Notfallhilfe verantwortlich sind? David Joshua Schröder geht dieser Frage nach, indem er sich der neuen räumlichen Gestalt dieser Orte soziologisch zuwendet. Ihren Wandel nimmt er nicht nur zum Anlass, um neue Arbeitsweisen herauszuarbeiten, sondern er tastet sich auch an die Frage heran, was sich aus diesen Veränderungen für die heutige Raumkontrolle in der refigurierten Moderne schließen lässt. Dabei zeigt er auf, dass Raum und Digitalisierung hier auf eine Weise verbunden sind, die keinesfalls zu einer allmählichen Auflösung dieser Orte führt.
